Abstract: ABSTRACT A molded cushioning article is made by stuffing a bulky, tape-form nonwoven web such as sliver in a mold cavity and thereafter heat-treating the thus-formed molded form to fusion-bond intersecting points of fibers. Stuffing of the tape-form nonwoven web is effected by laying and superposing it in to-and-fro movements on a molding surface of a mold permeable to air with a space on a backside of the molding surface being kept under reduced pressure. The apparatus used has (a) means for feeding the tape-form nonwoven web into the mold, (b) a mold permeable to air, (c) a mold-supporting frame, (d) suction means for keeping the backside space under reduced pressure, (e) means for successively changing a positional correlation between means (a) and the molding surface, and (f) heat-treating means for fibers to be fusion-bonded.

Abstract: Abrégé : Ce procédé d'analyse d'interblocages dans un système d'exploitation d'une machine utilise une méthode qui consiste à rechercher, pour toute unité d'exécution bloquée sur un verrou, l'unité d'exécution qui détient ce verrou et lorsque l'unité d'exécution est elle-même en attente sur un verrou à remonter la chaîne jusqu'à trouver un cycle. De façon remarquable, lorsque la machine comporte un multiprocesseur symétrique et fonctionne dans un environnement UNIX, ce procédé utilise de manière itérative une fonction spécifique qui permet de passer d'une unité d'exécution et de l'ensemble des processeurs vers tout type de verrous (en attente active ou passive) en parcourant l'une après l'autre les unités d'exécution pourreconstituer élément par élément un interblocage et donc un cycle. Il permet en outre, lorsqu'une mémoire virtuelle est utilisée et que toutes les informations utiles ne se trouvent pas en mémoire physique, d'assister un utilisateur pour agencer l'ensemble des chaînes fourni par ledit procédé pour reconstituer le cycle déterminant l'interblocage.

Abstract: Laissez-nous vous présenter notre invention qui consiste en un banc à utilités multiples tel que chevalet pour le personnel de la construction ou d'entretien de propriété. Pour les bricoleurs, pour les fermiers ou même être utiliser dans les usines ou usages personnels multiples. Ce banc d'utilité a la caractéristique de se plier après usage de façon très simple et facile afin de rendre le transport ou le remisage plus commode. Nous avons crus bon d'ajouter deux éléments à notre banc soit: un butoir pour retenir l'objet qui sera déposer sur le banc afin d'y exécuter des travaux. Aussi nous avons dessiné deux ancreurs donc un à chaque extrémité du banc, afin d'y insérerune pièce de bois ou d'autre matière à la largeur pré-choisi, dans le but de relever la hauteur du ou des bancs, pour ainsi s'en servir comme pieds de table en y ajoutant une planche ou un contreplaqué sur le travers des dits bancs. La plus grande particularité de notre invention est qu'il n'existe aucun boulon,rivet, clou, vis ou soudure pour retenir ou articuler les éléments principaux de notre banc. Ainsi nous avons tenté de simplifier le plus possible notre création et en rendre l'utilisation le plus facile qui soit. Lorsque plié, ce banc prend très peu d'espace et permet un remisage facile, il peut facilement être suspendu au mur du hangar ou ranger au sous-sol. Il est de conception très légère et tout ça malgré sa très grande robustesse et résistance au durs travaux.
